Hi! I am hoping to get some advice re casting. I don't understand the process fully, so I am a little confused.
I had made a wax ring in size N. I took it to a caster and he cast it into silver and I was happy with it. So I asked for 30 of the ring to be made which he did. I then asked about different sizes. So he made me wax models in 1x K and 1x Q as a favour but has said that I will need to make the model myself each time I want the different sizes cast. I asked if I can just get multiples cast from one wax model but he said no as there will be shrinkage. But then he had already cast 30x for the original N?! Can anyone tell me if this is right? I find it hard to believe that you have to make a wax model for every ring.
